Mechanical CAD Designer (TE-MSC-SMT-2026-195-LD)

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature.

Introduction

As a Mechanical CAD Designer in the Superconducting Magnet Technology section, you will develop three-dimensional computer-aided design (CAD) models and detailed drawings for novel superconducting magnets and associated tooling. Working closely with engineers and other technical specialists, you will take part in research and development projects for future particle accelerators. Your work will help transform innovative magnet concepts into manufacturable prototypes and practical assembly solutions.

Functions

• Prepare 3D CAD mechanical models and drawings of short magnet demonstrators, prototypes and associated tooling, in close collaboration with other colleagues in the section.
• Update CAD models and drawings to integrate feedback from construction and assembly activities.
• Contribute to technical discussions related to mechanical tolerances, machining methods and assembly procedures.
• Support procurement of components and update CAD models and drawings to reflect as-built configurations.
• Assist colleagues with tailored 3D models for computer numerical control (CNC) machining and simulations (electromagnetic, mechanical).

Higher technical diploma or equivalent relevant experience in the field of Mechanical Engineering or a related field.

Experience:

• Proficiency in CATIA (or a similar modern 3D CAD software), including the production of detailed 2D manufacturing and assembly drawings, for mechanical components and assemblies.
• Experience with a Product Lifecycle Management database (e.g. PLM, Enovia, SmarTeam) to manage models and drawings.
• Knowledge of mechanical assemblies and ISO-GPS dimensioning and tolerancing.
• Knowledge of superconducting magnet construction and technologies would be an asset.

Technical competencies:

• Knowledge and application of manufacturing methods and work preparation.
• Assembly of mechanical structures and equipment.
• Production of 2D drawings and 3D models.
• Knowledge and application of mechanical measurement techniques.

Behavioural competencies:

• Working in Teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities.
• Demonstrating Accountability: working conscientiously and reliably; delivering on promises.
• Demonstrating Flexibility: adapting quickly and resourcefully to shifting priorities and requirements.
• Learning and Sharing Knowledge: sharing knowledge and expertise freely and willingly with others.

Language skills:

Spoken and written English or French, with a commitment to learn the other language.
